Reconfigure Windows CIB cluster to CAB cluster

Hi all,

is it technically possible (and viable) to in-place reconfigure a Server 2012R2, 2-node, Windows Failover Cluster running a 'cluster-in-a-box' configuration with shared vmdk's on a single ESXi host to the same 2-node, Windows Failover Cluster running a 'cluster-across-a-box' configuration on 2 separate ESXi hosts?

For example.... migrating the vmdk's to RDMs (using vmkfstools), moving one VM to 2nd host and re-configuring both VMs to the new RDMs in Physical mode (but that sounds too easy) ?

Has anyone experience of doing this and can give pointers, advice (don't do it ) ?

Thanks in advance...
